commodification?

“Duality” of behavior is something I could never agree with and I have come to realize that its homogeny isn’t something too simple to comprehend or concur with either.
To a decent extent, the behavior of a person should depend on the person(s) being dealt with. Perhaps like our behavior vis-à-vis our family/ close friends has to differ from our behavior vis-à-vis our acquaintances. Uniformity of behavior with everyone you know just goes to show that you probably don’t have much to offer in terms of conversation, thoughts, ideas, company etc. Moreover, it also makes everyone around you feel as though they have been slated to a generalization…a sign of terrible soft skills.
I thought my, albeit platonic, relationship with someone was mutually exclusive. But when I hear these snippets of “my conversations” as a third person’s experience…it makes me wonder about the very nature of my relationship. I mean, WTF? It burns me up really…the very thought is obnoxious! I feel deceived…but I simply cannot challenge it. Heck! I am not even supposed to know about these “other” conversations. What people talk with others is none of my business. But it troubles me anyway.
What makes a relationship special? What makes them tick? What if all relationships were the same…and had the same thing keeping them in momentum? What if you shared a dozen identical relationships with 12 people who were acquaintances? How are they supposed to feel?
Really, WTF!! This is perhaps the most inconsiderate mean spirited experience I have ever had.
But, what you gonna do?
